Un inventor recibe ofertas de dos compañías por su tecnología y tiene que decidir cuál es la mejor oferta, tomando como punto de referencia su posibilidad de invertir al 14% anual. Oferta 1: $150.000 hoy y $200.000 dentro de 10 años. Oferta 2: $30.000 al final de cada uno de los próximos 10 años.
Answer:
La oferta 2 oferce el mayor valor final. Es la que debería ser aceptada.
Step-by-step explanation:
Dada la siguiente información:
Oferta 1:
$150.000 hoy y $200.000 dentro de 10 años.
Oferta 2:
$30.000 al final de cada uno de los próximos 10 años.
Tasa de interés= 14%
Para decidir cuál de las dos ofertas es mejor, debemos calcular el valor final:
Oferta 1:
VF= VP*(1+i)^n
VF= 150.000*(1,14^10) + 200.000
VF= $2.261.523,48
Oferta 2:
VF= {A*[(1+i)^n-1]}/i
A= cash flow anual
VF= {30.000*[(1,14^20) - 1]} / 0.14
VF= $2.730.747,83
A sport shop has 30 employees. 80% of the employees work part time. How many part-time employees does the sports shop have?
Answer:
they have 24 part time employees
Step-by-step explanation:
multiply 30 by .8 (which is 80% in decimal form) and you get 24. subtract that from 30 and you get 6 extra employees. 24 is the answer.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
100% = 30
80% = 24
The number of employees who work part-time is 24.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of employees = 30
80% of the employees work part-time.
This means,
80% of 30
= 80/100 x 30
= 24
Thus,
The number of employees who work part-time is 24.

Maggie claims that the function g(x) = - 4 is the inverse of the function of f(0) = 3a + 4.
Which statement provides a correct analysis of Maggie's claim?
Maggie's claim is correct because if you add 4 to g(x) and then multiply it by 3 you get
f(x)
Maggie's claim is correct because when g(x) is substituted into every occurrence of x
O in f(x), f(g(x)) = x, and when f(x) is substituted into every occurrence of x in g(x),
g(f(x)) = x
Maggie's claim is incorrect because when g(x) is substituted into every occurrence of
O x in f(x). ; therefore, g(x) is not the inverse of f(x), f(g(x))=x-8; therefore, g(x) is not the
inverse of f(x)
Maggie's claim is incorrect because when g(x) is substituted into every occurrence of
x in f(x), f(g(x)) = x; therefore, g(x) is not the inverse of f(x).
The inverse of a function reverses the operation of a function
The statement that provides the correct analysis of Maggie's claim is the following option;
Maggie's claim is incorrect because when g(x) is substituted into every occurrence of x in f(x), f(g(x)) = x - 8; therefore, g(x) is not the inverse of f(x)
Question: The functions in the question are presented as follows;
[tex]g(x) = \dfrac{x}{3} - 4[/tex]
f(x) = 3·x + 4
Required:
The statement that provides a correct analysis of Maggie's claim
Solution:
The inverse of f(x) is found as follows;
y = 3·x + 4
[tex]x = \dfrac{y - 4}{3}[/tex]
Therefore;
[tex]f^{-1}(x) = \dfrac{x - 4}{3}[/tex]
The inverse of a function above was found by making x the subject of the
function f(x), therefore, when the inverse f⁻¹(x) is substituted into all
occurrence of x in f(x), we get x
However, when g(x) is substituted into every occurrence of x in g(x), we get;
[tex]f \left (g(x) \right) = 3 \times \left (\dfrac{x}{3} - 4 \right)+ 4 = x - 8 \neq x[/tex]
Therefore, the given function g(x) is not the inverse of the function f(x) and the correct option is as follows;
Maggie's claim is incorrect because when g(x) is substituted into every occurrence of x in f(x), f(g(x)) = x - 8; therefore, g(x) is not the inverse of f(x)

can you please help if u can thanks
Answer: I will help you but if you try first.
Step-by-step explanation:
Answer:
y = 4x + 3
[ x ][ -2 ][ -1 ][ 0 ][ 1 ][ 2 ]
[ y ][ -5 ][ -1 ][ 3 ][ 7 ][ 11 ]
y = 4(-2) + 3 y = 4(-1) + 3 y = 4(0) + 3 y = 4(1) + 3 y = 4(2) + 3
y = -8 + 3 y = -4 + 3 y = 0 + 3 y = 4 + 3 y = 8 + 3
y = -5 y = -1 y = 3 y = 7 y = 11

The sum of two numbers is 72, and their difference is 40. Find the numbers.
Answer:
56 and 16
Step-by-step explanation:
Set up equations!
x+y=72
x-y=40
You can solve for this by crossing out y as it becomes eliminated. You are left with 2x= 112. Then solve, so x= 56. Take 56 for x and plug it into one of the equations and solve for y. 56-y=40-----> y= 16. The numbers are 16 and 56.
Using a system of equations, it is found that the numbers are 16 and 56.
The numbers are unknown, so we are going to call them x and y.Their sum is of 72, thus:
[tex]x + y = 72 \rightarrow y = 72 - x[/tex]
Their difference is of 40, thus:
[tex]x - y = 40[/tex]
Since [tex]y = 72 - x[/tex]
[tex]x - (72 - x) = 40[/tex]
[tex]2x = 112[/tex]
[tex]x = \frac{112}{2}[/tex]
[tex]x = 56[/tex]
Then:
[tex]y = 72 - x = 72 - 56 = 16[/tex]
The numbers are 16 and 56.

Investors buy a studio apartment for $150,000. Of this amount, they have a down payment of $37,500. Their down payment is what percent of the purchase price? What percent of the purchase price would a $67,500 down payment be?
Answer: To find the percentage of the down payment to the purchase price, just multiply the down payment by 100 and divide the result by the purchase
i.e 15,000 x 100/ 150,000= 10%
Also for the second part, multiply the down payment by 100 and divide by the purchase price
i.e 67,500 x 100 / 150,000= 45%

35% of the spectators at a baseball match are New York Yankees fan and the rest are Boston Red Sox fan. 30% of the fans in both teams are females. What person of the fans are both male and Boston Red Sox fan?
Answer:
Step-by-step explanation:
At a Baseball Match.
35% of spectators are New York Yankees fan
The rest are Boston Red Sox fan = 100 - 35% = 65%
30% of fans in both teams are females.
30% of 35% of spectators are New York Yankees fan = 0.105 females
30% of 65% of spectators are Boston Red Sox fan = 0.195 females
The number of males in New York Yankees fan = 1 - 0.105 females
= 0.895 males
The number of males in Boston Red Sox fan = 1 - 0.195 females
= 0.805 males

An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° f what is the rate of the temperature change in degrees Fahrenheit per foot complete the steps below to answer the question
Given :
An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° F.
To Find :
The rate of the temperature change in degrees Fahrenheit per foot.
Solution :
Let, rate of the temperature change in degrees Fahrenheit per foot is x.
So,
[tex]x = \dfrac{20}{1000}\ ^oF/foot\\\\x = 0.02 ^oF/foot[/tex]
Therefore, rate of the temperature change in degrees Fahrenheit per foot is 0.02.
Hence, this is the required solution.
Answer:
this is really late, but for the people who need it now the real answer is
Step-by-step explanation:
The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.
